MACHINE FOR DRILLING OR BORING ROCK kAND OTHER SUBSTA-NCES.

Speccatonof LettersPatent No. 1,672,7dated Jul-y 3, 1840.

vBe it known ythat 1I, SIMON Parras, of Schenectady, in the county of Schenectady and v'State of New York, have inventeda new and useful Machine for Drilling `Rocks and other-Substances, which'is describedas follows,'reference being had to the annexed drawings of the same, making p art ofthis specification. l

Figure l is a perspective View ofthemachine. Fig. 2 is a view ofthe underside of the head of the drill. Fig. '3 isa section of the cylinder containing the spiral spring. Fig. 4 represents one of the two lhooks or .eyes in the sliding -cylinder frame o through which the shaft CZ passes land `alsothe groove inV one` ,of the side pieces of said frame which admits therib o, and likewise representst-he tappets e on the shaft cl.

Similar letters referto similar parts in the figures.

.This machine -consists ,of a rectangular main frame A adjustable atpleasureto the unequality of the place where the boring is to be effected, by means of four adjustable sliding rods B placed in cavities in the .outside corners of the fourpostsof the frame and secured in any position desiredby eye screw-bolts C and nuts D, said rods passing through the eyes in said screw.

The drawing represents the frame placed on an inclined surface with two of its posts resting on the rock and two of the rods B extended downward and secured by the nuts and screws in order to bring the main frame A into an upright position. An inclined adjustable frame E containing the guides for the drill is placed inside the main frame A made adjustable at pleasure to bring it into any inclination required according to the angle that the hole is to be drilled by having parallel slots F F in m made in the parallel side pieces of the main frame A for screw bolts G to move in, projecting from the sides of the inclined frame and which are secured at any position desired by hand nuts H screwed on the ends thereof and; also grooves I in the side pieces of the inclined frame for the upper screw bolts to move in. The slots F mare for the screwbolts G1 G2 to move in while adjusting the frame E the screw bolts G1 having a simultaneous movement in both slots I and m, in changing the inclination of the frame E the slots'I and m allow the upper end of the frame E to describe a segment of a circle of a radius equal to the distance from the screw G2 which will be the center of lsaid circle and mayremain Xed in changing-.the .angleof the frame E.

.The-.lower guide K for the drill is ya crosspece secu-red near `the lower ends of :the

sides of the inclined adjustable frame E .and

has aunetallic plate L secured on the upper sidecthereof perforated with .a round aperture the diameter of the drill for it to pass freely through in rising andfalling. At the head of this frame is a windlass M for raising the cylinder frame V (hereafter 3des-cribed) on the end of which -is a ratchet wheel N into which drops a pawl O attached to the side. of the inclined frame and pressed into gear by-.a .spring l?.

The cylinder frame V is so called because it .carries the `cylinder Q containing the Spiral spring R screw S and buttons T T. It consists oftwo parallel side pieces V1 V2 united by two cross pieces V3 V 4 the `side pieces Vl V2 being `grooved-tov-allow-them to slide over two ribs V V fastened to the insideofthe inclined :frame E whichrserve as guides or ways: the cylinder is supported by;a piece of timber IV let into two larms or supportsn, n mortised and tenoned into .the sides of the inclined cylinder frame V at right angles thereto.

The spiral spring R inside the cylinder is placed between two buttons T T of the diameter 0f the bore of the cylinder in which they move-the upper one being pressed down by a screw S with a crank handle said screw passing through the head of the cylinder. The lower button (when the drill is down) rests upon a projecting circular ledge t inside the cylinder near the lower end thereof which is open. The screw is for contracting the spring and giving it more force in driving down the drill.

The drill a is made in sections with sockets and shanks secured by screws so that it can be lengthened as the work progresses. The upper section has a large round flat cast iron head b having triangular or curved cams 01 02 on the under side for the tappets e' on the horizontal shaft Z (hereafter described) to strike against which causes the drill to turn around at the same time that it is lifted by said tappets. The upper end of the drill is made smaller than .the inside of the cylinder so that it shall pass easily into it without touching the before mentioned circular ledge t. The cams 02 are made pointed of a wedge form with the'three sides of each curved as represented in Fig. 2.

The propelling shaft d extends horizontally through the frame A` andA turns in hooks g or boXes fastened to the sliding cylinder frame by a `crank by hands or other power. These hooks are not seen in Fig. 1grr one of them is representedin Fig; 1l. The tappets e for raising the drill are fastened to and radiate from this shatt,l and in this arrangement are three in number but they may be increased or diminished in` size and number at pleasure and of any convenient shape, either straight or curved. Thev shaft is also provided with fly wheels f f to equalize the motion. i

The chains or cords g g for raising the Vcylinder frame are attached to the head thereol:I and are wound around the windlass which is turned by hand-spikes L or other means-and when it is required to remove the drill the windlass is turned which raises the cylinder from over the drill. The spiral spring may be coiled around the drill below the cylinder which will answer the same purpose as placing it inside the cyl-A a of the drin a andra it and in rising its i Vforce of the contracted spiral spring in eX- tending itself causes `the drill to strike the rock with great force and this operation being repeated soon cuts a `hole in the rock and' as the work progresses the cylinder and springare lowered to thedrill by lifting the I pawl, reversing the movement of the windlass and unwinding the cords gand when the drill is required to be lengthened by the insertion of a shank and socket the windlass is turned to the right which winds up the cords and raises the cylinder rame with the cylinder from the head of the drill which thus allows the operator an opportunity to adjust the length of the drill for a continuation of the work or for any other object that may be required. y

l/Vhat I claim asmy invention and desire to secure by Letters Patent is The combination `of the inclined adjust? able and sliding frames E, V with the drill a as constructed, in the manner described and also the method of raisingand turning the drill by means of the cogs or cams C2 on the plate b and the tappets e on the shaftd as herein described. l i i SIMON PETTES.`
